First things first, hello all. I'm new here...just signed up.
I have a 2008 GT with a full Mac exhaust (longtube headers, offroad prochamber, axlebacks) and let me tell you, I had a 93 tune before the exhaust install and it was pretty quick. The difference in throttle response after i put the full exhaust on was pure violence.
If you get headers, I recommend longtubes. Just my opinion.
